。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a gasification power plant, and particularly to a high temperature heat utilization system suitable for improving plant thermal efficiency.

するガス化発電プラントの開発が行なわれている。Low-quality petroleum fuel, coal, etc. is gasified with an oxidizing agent such as oxygen or air, the gasified fuel gas is purified by a gas purification device, and the purified fuel gas is used as gas turbine fuel. Gasification power plants that drive combined cycle power generation are being developed.

ントの利点を生かすためにはガス化炉よ多発生する燃料
ガスの顕熱を蒸気サイクル以外で回収する必要がある。Various types of gasifiers are being planned, but the one that is currently considered promising is the spouted bed type. This furnace is characterized by the fact that the impurities in the fuel are removed from the bottom of the furnace in a molten state, so it is necessary to maintain the temperature inside the furnace at a high temperature. Therefore, the fuel gas flowing out of the furnace is at a high temperature (approximately +aooc).
Therefore, it is necessary to generate steam using a heat recovery device and recover sensible heat from the heating gas. In such a system, a large proportion of the heat input to the system is used by the steam turbine plant, reducing the advantage of a combined gas turbine-steam turbine plant, which is more efficient than a steam turbine. In order to take advantage of the advantages of a gas turbine/steam turbine combined plant, it is necessary to recover the sensible heat of the fuel gas that is generated in large quantities in the gasifier using a method other than the steam cycle.
本発明の目的は、ガス化発電プラントにおいて。 The object of the invention is in a gasification power plant.
